Specification of Letters Patent.

Patented May 4, 1915.

Application filed December 5, 1912. Serial No. 735,061.

To all 1071 am it may concern Be it known that I, SHERMAN T. BROWN, acitizen of the United States, residing at St. Paul, in the county ofRamsey and State of Minnesota, have invented certain new and usefulImprovements in BoX-Flanging Machines, of which the following is aspecification.

My invention relates to improvements in machines designed particularlyfor gluing flanges upon boxes or covers, and consists particularly inmeans for positioning and bringing together the component parts to beglued, and a mechanism for supplying the glue and pressing the gluedparts together.

To this end the invention consists in the features of construction,combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure1 is a right hand side elevation of my improved machine; Fig. 2 is a topview of the placing and gluing portion of the machine; Fig. 3 in asection on line w0a of Fig. 2; Fig. 4 is a perspective view,intermittent gearing forming part of the driving gear; Fig. 5 is a topView of the flange placing portion of the machine; Fig. 6 is a detail ofa tilting arm forming part of the mechanism shown in Fig. 5; Fig. 7 is atop view of the press ing or delivery portion of the machine; Fig. 8 isa front view'of the gluing portion of the machine broken. away; Fig. 9is a rear View of the parts shown in Fig. 8; Fig. 10 is a rear view ofthe machine showing the placing and gluing mechanism with part of thegluing mechanism removed; Fig. 11 is a plan view of part of theoperating mechanism of the machine; Fig. 12 is a rear view of part ofthe mechanism shown in Fig. 11; Fig. 13 is a rear view of a camoperating shaft forming part of the mechanism; Fig. 14 is a rear view ofshaft mechanism associated with the shaft mechanism shown in Fig. 13;Fig. 15 is a rear view of idlers forming part of the operatingmechanism; Fig. 16 is an end view of a flange holder and connected partswith part of the supporting framework shown in section; Fig. 17 is asection on line yy of Fig. 5, with flange positioning arms removed; Fig.18 is a rear view of the flange holder and delivery devices} Fig-19 is afront View of the same;

Figs. 20, 21, and 22 are detail views of flanged positioning arms; Fig.23 is a detail of a flange delivery rail; Fig. 24 is a detail of a frontsupport; Fig. 25 is a rear support of the rail shown in Fig. 23; Fig. 26is a detail View of a flange delivery slide; Fig. 27 is a section online row of Fig. 26; Fig. 28 is a rear view of the pressing and deliveryend of the machine; and Fig. 29 is a vertical section through Fig. 28.

Referring to the drawings, A represents the supporting framework of themachine. Passing over sprockets 2 and 3 secured upon shafts 4 and 5having journal support in the opposite ends of the machine are the gearchains 6. Arranged in connection with the supporting shaft of thesprockets 3 is a suitable take-up device 7. Secured along the carrierchains are interspaced blocks 8, the blocks being each formed with a rib9 extending inwardly between the chains. Each rib 9 is formed with sidegrooves 10 to receive the rails 11 extending longitudinally of the bedof the machine, whereby to form a steady support for the blocks as theytravel over the bed of the machine as indicated in Fig. 1. The shaft 4is operated from the main shaft B through the medium of a secondaryshaft 14, gearing 13 connecting the secondary shaft with the shaft 4 andstep down gearing 12 between the main shaft and secondary shaft.Included within the gearing 13 are the intermittent gears 15 and 16,whereby to impart step by step travel to the carrier chains. Supportedby the framework adjacent to the feeding end of the machine is themechanism for placing glue upon the unflanged.

boX or cover which is placed upon the block before the same reaches thegluing apparatus. Included in the gluing apparatus is a glue holdingtank 17 supported by the framework at one side of the machine. Withinthe tank is journaled a pair of superimposed rollers 18 and 19 overwhich runs a belt 20, which belt engages with an adjacently journaledroller 21. The roller 21 is actuated from the longitudinal shaft 22having journal support below the bed of the machine a cable 23connecting said roller and shaft. The shaft 22 has gear connection 24with the shaft 14, the gearing 24 including intermittent gears 25 and26, similar to the gears 15 and 16. Adapted to "be reciprocated over theglue rollers 20 and 21 and inwardly over the top of the adjacent top orbox supporting block is a glue roller 27 supported upon the end of anarm 28, which arm at its opposite end 1s pivotally supported upon anelbow 29. The elbow 29, at its lower outer end, has pivotal support 30in brackets 31 extending downwardly and outwardly from the framework.The elbow is turned upon its pivotal support from dotted to full lineposition shown a in Fig. 3, and vice versa by means of a link 32connecting the elbow above its pivotal support to a knuckle offset fromthe longitudinal shaft 34 journaled underneath the bed of the machine.The shaft 34 has gearing connection 35 with the drive shaft 1 1, thegearing 35 including intermittent gears 36 and 37 similar to theintermittent gears 15 and 16. Mounted on the ends of the shaft of theroller 27 are guide rollers 38 which travel upon the rails 39 extendingtransversely above the bed of the machine.

Slidably supported above the rails 39, through the medium of an elbowarm 40, is a glue receiving plate &1. The downward extension of the armd0 slides in a guideway 42 and is adapted to be engaged at its lower endby a cam 43 mounted upon the longitudinally extending shaft 44 jour-'naled below the bed of the machine. The shaft 44 has chain and sprocketconnection 45 with the heretofore described shaft 22. The parts arearranged to so cooperate that, while the block supporting the unflangedbox or cover is traveling to position below the glue receiving plate 41the gluing roller 27 will be carried from the glue receptacle across theunderface of the plate 41 and then back from under said plate. The shaftf lwill then be actuated to turn the cam out of engagement with the armL0, allowing the plate 41 to drop upon the top of the unflanged box orcover and deposit the aglue thereon, the continued turning of the shaftcausing the cam to engage and raise the arm 40 with its supported gluedepositing plate.

From the gluing mechanism the block is carried forward one step to theflange delivery mechanism shown particularly in Figs. 5 and 16 to 26.Supported upon the framework at one side of the machine is an open topand open bottom receptacle d6 for holding a superimposed plurality ofbox flanges 5L7. Horizontally adjustable within the holder are side,front and rear centering devices 48, 49, and 50. Each of the centeringdevices extends downwardly withthe centering devices are formed withinwardly extending flanges supporting lips 43% and for the box flanges.

For the purpose of shoving the lowermost box flange outwardly over thead acent box or cover supporting block and depositing said flange uponthe unflanged box or cover 56 I provide the following parts: Slidablethrough the bottom of the flange holder is a delivery slide 57, saidslide being ,:i,i.'wardly tapered and being adjustably supported upon across bar 58 by means of the adjusting screw 59. its ends is supportedin longitudinally extending slots (30 in the lower ends of lever arms61, the upper ends of the lever arms having fulcrum support 62 upon thesides of the holder. The upper ends of the lever .arms 61 are formedwith downward and outward crank extensions 63 connected by rods 64: witheccentrics 65 secured upon the shaft 34.

Extending transversely above the bed of the machine in line with thesides of the flange holder are rotatably supported tumbler rails (36,each formed upon its inner side with a groove 67, and each railsupporting a disk 68 at its outer end.

In Fig. 24 is represented a bearing box (39 for the outer end of eachrail and in Fig. 25 is represented a bearing box 70 for the opposite endof the rails being formed with a groove 71 to coincide with the groove67 in the rail. The disks 68 of the tumbler rails carry crank pins 72fitting in the horizontal' slots 73 of the vertically slidable plate 71-, the plate 7% being slidable in a suitable bracket 75. The plate 7%is reciprocated through the medium of rods 76 connecting said plate witheccentrics 77 supported upon the shaft let. The delivery slide 57 in itsoutward movement slides through an opening 78 in the lower end of thecentering device 50 and at its forward end is preferably formed withgrooves 79 to receive the lowermost flange.

The parts are adjusted to so operate that the delivery slide will becarried behind the flanges in the holder, the relative thicker front ofthe slide raising the flanges until the slide is carried beyond them,when the flanges will drop and the lowermost flange stand in front ofthe groove in the slide. The continued operation will carry the slideforward, as shown in Fig. 17, to carry the lowermost flange into thegrooves of the tumbler rails. The tumbler rails will then be rotated bythe operating mechanism to drop the supported flange upon the unflangedbox or cover.

From the flange delivery and depositing mechanism the operatingmechanism will carry the blocks with. the supported flanged box or coverunder the pressure plate 80. The plate 80 is adjustably supported inthe,

The cross bar at cross bars 81 through the medium of screws 82 threadedthrough said cross bars and provided with handles 83. The cross bars 81are raised and lowered through the medium of the rods 84 and 85connecting said cross bars with the eccentrics 86 and 87 mounted,respectively, upon the shaft 44 and a parallel shaft 88 journaled belowthe bed of the machine. The shaft 88 is 1'0- tated from the shaft 44through the medium of sprocket and chain connection 89. Thus in theoperation of the machine the rotating of the shaft 44 will cause therotation of the shaft 88 and the lowering of the cross bars 81 to bringthe plate 80 into engagement with the flange of the box or cover andpress the flange and box or cover together to cause them to firmlyadhere. The vertical adjustment of the plate 80 is utilized inregulating the height of the plate for different thicknesses of flanges.

C indicates an actuating handle for clutch mechanism, not shown,arranged in connection with the drive pulley 90 to pull the same intooperative connection with the main shaft.

In the operation of the machine the unflanged box or cover 56 will beplaced upon the block 8 at the feed end of the machine. The step by stepoperation of the machine will carry the block and supported unflangedbox or cover into the position shown in Fig. 3. ile coming to thisposition the roller 27 will first be actuated to be carried from theglue pot across the bottom face of the plate 41 and then back over theglue pot. The actuating of the cam 43 will then release the platesupporting arm allowing said plate to drop on the unflanged box or coverto deposit glue thereon, the further turning of the cam 43 then raisingthe plate 41 into the position shown in Fig. 3.

The continued step by step operation of the machine will carry the blockinto the position shown in Fig. 17 In this position the delivery wedge57, standing behind the lowermost flange, will be actuated to shove saidflange forwardly into the grooves of the tumblers 60, the delivery wedgethen being carried back to withdrawn position. As the delivery wedge iscarried underneath the flanges the thickened front end thereof willraise the flanges so that as the wedge passes beyond the flanges theflanges will drop to bring the lowermost flange in front of the deliverywedge ready for another operation. As soon as the delivery wedge iswithdrawn the tumblers will be rotated by the hereto-fore describedactuating mecha nism to drop the supported flange upon the unflanged boxor cover. The step by step operation of the machine will then carry theblock and supported box or cover underneath the pressure plate 80. Theplate will be lowered making the mechanism heretofore described pressthe flange tightly upon the box or cover to glue said parts together.

The different operating parts of the machine described are arranged toso cooperate that the supporting block will be carried by said step bystep movement tothe gluing mechanism, thence to the flange deliverymechanism and from there to the pressing mechanism. Similarly theoperating mechanism for the gluing mechanisms is timed to properlycooperate with the step by step travel of the blocks. By means of theadjustable centering devices for the flange holding receptacle, flangesof different sizes may be employed.
